Environmental management

Updated: 22 January 2010

New Zealand's transport system provides us access to social, educational, employment and recreational opportunities. However, the construction of transport infrastructure and our high use of vehicles (that use petroleum products as their energy source) have significant environmental and social impacts.

In our planning we seek to avoid, remedy or mitigate against environmental and social adverse effects.

Social responsibility

New Zealand's transport system provides access to social, educational, employment and recreational opportunities and, in this way, contributes to the wellbeing of communities.

However, the construction, operation and maintenance of the transport system can have negative social impacts. This includes the creation of severance by roading projects in areas where people need to move between different activities and existing land uses. There are many ways to support community cohesion by improving land use accessibility, affordability and transport diversity.

Environmental responsibility

Transport generates a number of adverse environmental effects from both transport infrastructure and vehicles. The effects, which can be direct, indirect and cumulative, include:

  • greenhouse gas emissions
  • air pollution
  • discharges to land and water
  • amenity impacts
  • the use of non-renewable resources
  • land take
  • biodiversity losses.

The Resource Management Act 1991 (RMA) is New Zealand's primary environmental statue and establishes a framework within which the environmental effects of our activities can be identified and properly dealt with. When developing, maintaining and operating transport infrastructure both central and local government are required to comply with the RMA.

We've produced many research reports examining the environment effects of transport and how to avoid, reduce and mitigate these effects.

We must ensure that we avoid, remedy or mitigate our effects on the environment during the planning, construction, maintenance and operation of the state highway network.

Our environmental plan (PDF, 102 pages, 4.63KB) sets out our strategic environmental vision to enable us to set specifications and standards for our contractors undertaking roading works. The plan is also available to help and guide other land transport operators.
